This makes more sense. I have wondered how the one-way air flow would work...are there check valves to ensure the air only passes on way? If not, what would make them flow only one way?

I would love to see you rebut the contentions made by the TIGHAR (Earhart ditched on Gardner Island). They have a lot of evidence regarding post-crash radio traffic analysis that makes a reasonable case for their theory. Nice job.

This seems to be correct

really well done video

Aliens

I think storks crossing the pass of Gibraltar could learn a thing or two from the albatross genious way of dynamic soaring. In return storks could show the albatrosses how to use hot air collums on dry lands. Different birds with different ways to achieve effortless soarings...

Earhart seems to have had insufficient confidence in Noonans abilities which probably led to tension between the pair. Also the USCG didnt treat the flight with the necessary degree of importance until the aircraft disappeared but by then it was too late. The rest was down to bad luck and judgement.

Very thoughtful and interesting, but like all serious theories, relies too much on speculation. Also of course does not take into consideration the theorised messages for some days following the disappearance.

E X C E L L E N T .

I don't beleive Amelia was captured by the Japanese. They may have aided on her search. The US was not at war with Japan. And if they located and rescued her and her Navigator. In the eyes of the world back then . They would have showed superior Naval rescue tactics.

VERY NICE W0RK🎉

You could have saved yourself a lot of time making this video. The piano in the background is soooooooo damn loud, that it is difficult to understand your explanations. So you could have also remained silent and let the stupid piano play the whole time, the result would have been the same. I hope you consider the priorities in your future videos, this one sucks.

1:05 The Sun line across Howland rotated so as to stay perpendicular to the azimuth of the sun. The Sun passed north of Howland Island. So it rotated counterclockwise. The angular height of the Sun could be predicted for any instant that morning. If measured, its measured height could be compared with the prediction. The difference in arcminutes could be used to indicate how far the plane was left or right of the Sun line.

As a former USAF navigator with celestial navigation experience, this story has always interested me. It was a challenging flight given the weather and equipment of the time. Sometimes when you push the limits, bad things happen.

Imagine being sure that flying west would bring you back to land but your superior won't hear of it. Your sense of self-preservation tells you to break off and head west anyway, then your brain reminds you what happens to people who disobey orders. So you fly along, watching your fuel get lower and lower as your superior leads you out into the dark Atlantic.

@before 12:04, or, they were already South but didn't realize it. They turned South, thinking they would fly over Howland, when instead, they were flying into Nikamoro. Where ever they were, they were not close enough for anyone on the ground or on the Ataska to see or hear the plane.

Are there radioactive tracer studies that demonstrate initial movement to all air sacs simultaneously? Or is there experimental evidence, not simple conjecture based on anatomy observations? Is it possible that respiration and occur in a countercurrent unidirectional flow during flight and bidirectional at rest?

If only GPS had existed then 😞

Hi from New Zealand!🇳🇿Great doco!✈️

This video is so relaxing 😌🥰

Thank you so very much indeed for making this two-parter - I thoroughly appreciated your explanation of what happened? Everyone has and is entitled to their own opinions and for me your efforts are well packaged and give good credibility to one of the many conclusions need to be considered

Earhart mentioned "line of position 157 337." A sun line that crosses Howland is not necessarily an advanced sunrise line. Course deviation while tracking along a Sun Line that crosses over Howland is found by finding the difference in arcminutes between the Sun's observed height and calculated height.

As a former USAF navigator with celestial navigation experience, this event has always interested me. Thanks for sharing.

Noonan said the night before the trip they could only carry 950 gallons total. This must include the 100 octane fuel for the boost at takeoff from the unpacked runway at Lae because at 950 gallons, the plane was maxed out at the 15,300 pound capacity for a runway as short as that at Lae. With 950 gallons, they couldn’t have stayed in the air all of this time and distance. Especially with the headwind.

Avian respiration and its efficiency is remarkable. This is one of the simplest and best explanations.

Until we know, we don't know.

very good video, except TIGHAR is way off and you should not be using their data. They put Earharts plane on Gardinar island successfull landing.

Excellent display of DS and the flight of the albatross is amazing! In RC gliders there is a type of slope soaring called Dynamic soaring. The gliders are very large, heavy made of exotic material and are very strong. In DS there are no motors to assist the gliders and by using the same principle you described they have reached speeds over 500 mph in fact the record is 548mph from the power of the wind alone and some other forces as well lol!. Impressive!!! Now in terms of actual bird speed can the albatross go faster when the wind speed is higher? Great video... Thanks!

Thank you so much!

There is some factual data that you ignore or are unaware of. 1. No life raft onboard. Earhart had the aircraft stripped bare at Lae. She wanted the most range she could get. This is from testimony of the station manager at Lae and Earhart’s diary she mailed home. She reported details back to the US at every stop if possible. 2. There was not 3 hours of fuel onboard when they arrived in the vicinity of Howland. Not even close to that amount. Earhart kept meticulous records of her aircraft’s performance. She conferred with Kelly Johnson regularly to get the best performance. You do mention Johnson in Part 1. Not sure how you determined 3 hours reserve. Her exact fuel load is known from receipts at Lae. 3. The DF on her aircraft did not work on a test flight at Lae. This was obviously before her final take-off and the infamous puff of dirt from a dirt runway. She was mishandling the one-off, custom built Bendix radio. This was determined afterwards by the man who designed it. There are a couple of other details I won’t mention. I’m considering producing my own TH-cam video on this subject.

Excellent research and presentation. The sighting of the SS Myrtlebank and the radio report from Nauru was the defining proof for me that Earhart was tragically off course.

She did have 500 khz, retuned in lae for use with the rooftop antenna. The morse keys not on board , just meant tbey had to use tbe mic button to send crude morse, And they did , but not on 500 khz

Very well done and informative video, Colin! Your theory seems better than most. The one thing I realized when I did a virtual flight using celestial navigation from Bougainville to Howland (on MSFS in a DC-6), is that you can get within 7 miles of the island and not see it, if at or below 1,000' MSL. So, without some kind of radio homing signal, it would be very easy for them to miss the island. Even on non overcast days, the typical formation of numerous cumulus clouds cast shadows that makes the island itself look like just another cloud shadow.

What about the bones and artifacts, Including parts of the actual aircraft that were found on Gardener island?

Excellent video.

I wonder how many people know that magnetic north on the west coast of the US is different from the magnetic north on the east coast?

Here's my understanding of Earhart's radio situation: Her Western Electric transmitter was designed for voice only, but had been modified for morse code also. It had 3 selectable frequencies, 500 kHz, 3105 kHz, and 6210 kHz. It could be used with the "V" antenna atop the airplane on 3105 and 6210, but the trailing wire antenna was needed for 500 kHz. On the eastward trip, in Miami, the morse key and the trailing antenna were removed, the "V" antenna was lengthened a couple feet, and a large loading coil was installed so the transmitter would load up on 500 kHz. So she had the capability to transmit on 500 kHz, if she had wanted to. She also had the capability to receive on 500 kHz, certainly using the Bendix DF loop. The Itasca could not transmit voice on 7500 kHz, but, had Earhart left the antenna switch in the "loop" position while listening for Itasca's voice transmissions on 3105 or 6210, she very likely would have heard them. And had Itasca agreed to try transmitting their beacon on 500 kHz, 400 kHz, 333 kHz, or some other low frequency, she likely would have gotten a null. As with most aviation accidents, a chain of events led to this one. (1) She tested the DF (good), which leads me to believe she knew she would be relying on it at Howland. She was unable to get a null at Lae, the test failed, but she took off anyway, not understanding why it failed. (2) She took off over gross weight at Lae. As her airplane rolled over the rough ground of the grass strip, it is likely that her gear struts collapsed more than normal, and the receiving antenna was ripped from the underside of the airplane. Rather than take off overweight, she should have planned an intermediate fuel stop before Howland, a planning error which occurred before she even started. (3) There is no record that she tested the DF or communications enroute while she still had enough fuel to divert to an alternate. Or time to troubleshoot the problem. Although her choice of 7500 as the beacon frequency was a flight planning error which should have been corrected before she left the ground, by moving to a frequency more suited to her DF loop, such as 400 kHz. Had one or more of these errors been corrected before she left Lae, it is more likely she would have landed safely at Howland.

For anybody that knows radios, as she was taking off from Lae at small cloud of dust was seen on video. It was their receiving antenna that was torn off. They could not receive messages from Itasca.

How could a navy ship have no flares? Is it because they wanted to be incognito from the Japanese?

Great presentation, it looks like you’re the grand prize winner. They did in fact, find Amelia’s plane, well done.

What was the sea state at the time that Amelia supposedly ditched? If it was smooth, then she laid down nice and easy, and they could’ve gotten into a raft, but in 6 foot seas they probably got beat up, pretty bad and weren’t able to set up the raft

A UFO tu the aquatic life

They say that the Electra would not float for long. But I wonder. The plane was full of empty fuel tanks. Wouldn't those empty tanks have kept them afloat for at least some length of time? If the radio was not submerged couldn't they have sent out distress calls while drifting on the ocean?

Japanese Military could of capture them and sent to Saipan....they have died There or they lived and went on with assumed names were sent to somewhere by the US military...in 1944 the plane was destroyed by US Marines

3105khz and 6201khz are not good in the morning 🌅. ..they should have been on 8mhz and 13mhz... doing the day it was a bad choice 😮

Why she was down there?....it is all atolls... they were there to spy on the Japanese....in 1937....the Japanese government was planning War on the United States...the plane was on Saipan in 1944..my dad stated that for years. The plane was destroyed by the United States Marines in Saipan

So close but so far. That plane could be in a hundred pieces strewn on the seabed.

wow thank U very much. Fantastic informations with very fine visualisation. merci ...

Go take a look at the aircraft wreck at Buka island...Of all the theories telling us what happened to Amelia and Fred...Buka theory is the only one with a plane..an actual plane sitting at roughly 100ft deep on the bottom..Lockheed has taken very solid interest in the plane...human remains have been recovered and tested as belonging to a white western male...better yet...go to 'project blue angel' and look for Bill Snavely Amelia Earhart...could there have been 2 electras? If so..then the confusing navigation and radio communications could begin to make sense. Further...70% of Amelias flight path AFTER leaving Lae was never searched at the time of her going missing...ALL searches have begun with searching from where its assumed she went down...but no searches between Lae and that assumed crash&sink or landing at Nikumororo
